| Questions And Answer | Back Directory | [Description]
VH298 is a potent VHL (Von Hippel-Lindau, the E3 ligase) inhibitor that stabilizes HIF-α. VH298 blocks the VHL:HIF-α interaction with Kd of 90 nM in isothermal titration calorimetry (ITC) and 80 nM in a competitive fluorescence polarization assay. VH-298 can be used in PROTAC technology. | [In vitro]
VH298 can activate the HIF-1 signalling pathway by stabilizing both forms of HIF-1α in vitro. VH298 promotes rFb variability, migration, and synthesis of collagen and regulatory cell factors. VH298 improves the angiogenesis of hUVEC. | [In vivo]

(2S,4R)-1-((S)-2-(1-Cyanocyclopropanecarboxamido)-3,3-dimethylbutanoyl)-4-hydroxy-N-(4-(4-methylthiazol-5-yl)benzyl)pyrrolidine-2-carboxamide is a VHL inhibitors that decreases hypoxia inducible factor-α during hypoxia associated signaling in human cervical cancer, osteosarcoma HeLa and U2OS. cells. | [reaction suitability]

HIF-1α and hydroxy-HIF-1α levels increased in VH298-treated rFb in a time- and dose-dependent manner. Thirty micromolar VH298 could significantly increase cell proliferation, angiogenesis, and gene expression of type I collagen-α1 (Col1-α1), vascular endothelial growth factor A (VEGF-A), and insulin-like growth factor 1 (IGF-1). The VH298-treated wound had a better healing pattern, activation of HIF-1 signaling, and vascularization. It is is a potent VHL inhibitor that stabilizes HIF-α and elicits a hypoxic response via a different mechan: the the blockade of the VHL: HIF-α protein-protein interaction downstream of HIF-α hydroxylation by PHD enzymes. It engages with high affinity and specificity with VHL as its only primary cellular target, leading to selective on-target accumulation of hydroxylated HIF-α in a concentration- and time-dependent fashion in different cell lines, with subsequent upregulation of HIF-target genes at both mRNA and protein levels[1-2].
